Why aging T cells fail: implications for vaccination.

abstract：:Mutations affecting the Tec kinases Itk and Rlk decrease T cell receptor-induced Ca(2+) mobilization and Erk kinase activation and impair both positive and negative thymic selection. Itk(-/-) and Rlk(-/-)Itk(-/-) mice also have decreased CD4:8 T cell ratios, suggestive of altered CD4:8 lineage commitment. Nonetheless,...
